Note I have tried using the .run offline installer of Qt 5.6/5.9/5.11, what seems to happen is that they work on Ubuntu 16.04, 17.10 but fail on 18.04 - this is the stacktrace for reference https://pastebin.ubuntu.com/p/Yzj5gsmwQ3/
So it seems possible that it might be some underlying change to the platform (maybe something like dbus? or a new config/dir I need to enable). Furthermore it looks like this issue may affect Qt applications when they try to run as a snap under the core18 snap. https://github.com/snapcore/core18/issues/4 ** Bug watch added: github.com/snapcore/core18/issues #4 https://github.com/snapcore/core18/issues/4 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1774739 Title: Running Qt apps inside a 18.04 container crashes Status in qtbase-opensource-src package in Ubuntu: New Bug description: What happened: 1) Install a container system (eg Docker, LXD) - I'm using Docker 2) Create a container which is Ubuntu 18.04 3) Install a Qt app, eg qtcreator, inside the container 4) Run the container so that it shows the hosts X11 socket 5) Notice that the application fails to start What I expected to happen: At step 5 for the application to start.
